from an article in Science by Lloyd Keigwin of the Woods Hole Oceanographic
Institution [32]. Keigwin called the use of his data “very misleading” [42]. They
were a historical reconstruction of sea-surface temperatures in the Sargasso Sea
and, in his words, “not representative of the planet as a whole [as the advertorial
could be taken to imply]. To jump from the western North Atlantic Ocean to the
globe is something no responsible scientist would do…There’s really no way
those results bear on the question of human-induced climate warming….”
• A 1996 advertorial claimed that “greenhouse-gas emissions, which have a
warming effect, are offset by another combustion product – particulates – which
leads to cooling” [43]. In 1985, ExxonMobil scientists had reported being “not
very convinc[ed]” by the argument that “aerosol particulates . . . compensat[e]
for, and may even overwhelm, the fossil-fuel CO2 greenhouse warming” [19].
By 1995, the IPCC had rejected it.
Q14: What are the impacts, if any, of your findings and conclusions to the body
of climate science and current discourse on climate change?
A14: Our work does not stand in isolation, but complements and corroborates
earlier investigations. At the onset of our study, substantial evidence from
investigative journalism and scholarly research suggested that ExxonMobil
had misled the public on a variety of aspects of climate change and in a
variety of ways [1,44–53].
The purpose of our investigation was to bring to bear an additional,
complementary empirical methodology to test the hypothesis that
ExxonMobil had misled the public; namely, the first empirical assessment
and intercomparison of ExxonMobil’s private and public statements on
climate change. It may therefore be relevant to ongoing and/or future climate
litigation or investigations.
Our study was also designed to respond to ExxonMobil’s claim that relevant
documents (supplied by ExxonMobil) would exonerate the company. Our
results affirm the reverse: the documents that ExxonMobil proffered provide
strong evidence that journalistic investigations of this matter have been
largely correct.
By applying the quantitative methodologies of consensus measurement and
content analysis, our results add to (i) earlier analyses of ExxonMobil’s
communication practices, (ii) qualitative accounts of the company’s climate
change communications, and (iii) the application of consensus
measurement/content analysis to climate change communications. In
addition, this study contributes to the broader literature on climate change
denial, corporate issue management and misinformation strategies, and the
social construction of ignorance. Our study was reportedly one of the ten
“most talked-about climate change-related papers” of 2017 [54].
Q15: Based on your findings and conclusions, would you say that ExxonMobil’s
communications, specifically its “advertorials” about climate change,
